Description

Technical Field

[0001] The utility model relates to the technical field of roads and bridges, in particular to an assembled road and bridge pier structure. Background Art

[0002] Road bridges are generally composed of several major parts, including roadbed, pavement, bridges, tunnel projects and traffic engineering facilities.

[0003] In contrast to publication number 202023259748.3, a road bridge pier structure is disclosed. A connecting assembly is provided, and workers place the connecting assembly between the lower surface of the bridge body and the outer surface of the pier body. A plurality of I-shaped grooves 1 are provided on the upper surface of the L-shaped connecting plate and a side surface close to the pier body, and an I-shaped groove 2 is provided on the lower surface of the bridge body and the outer surface of the pier body at the position corresponding to the I-shaped groove 1. An I-shaped piece 1 is used in conjunction with the I-shaped grooves 1 and 2, and concrete is injected into the interior of the installation shell through the grouting hole, so that the interior of the installation shell is filled with concrete, so that the connecting assembly can be strengthened and fixed. The I-shaped groove 4 provided inside the fixing ring and the I-shaped groove 3 provided on the outer surface of the pier body are used, and the fixing ring is fixed to the outer surface of the pier body through the I-shaped piece 2, and fits with the lower surface of the installation shell, thereby strengthening and fixing the installation shell and the connecting assembly, so as to solve the problem that the lateral constraint on the main beam is weak and the stability is weak in the above-mentioned background technology, and the pier body may suffer from lateral overall instability under the action of overload eccentric load. Under the condition of large eccentric load vehicles or earthquakes, the bearings may become empty, causing major accidents such as lateral overturning of the main beam. It effectively improves the stability, has a simple structure, and is easy to operate. It solves the problem of weak lateral restraint and stability of the main beam. Under the action of overload eccentric load, the pier column body may suffer from lateral overall instability.

[0004] This road bridge pier column structure is effectively improved in stability with a simple structure and easy operation.
